Iron He-triplet signatures of shocks in the hottest galaxy clusters. Z/W line ratio, line broadening, and electron-ion temperature equilibration

Eugene Churazov, Yuri Ralchenko, Ildar I. Khabibullin +5

A merger of clusters naturally drives shocks with Mach number in the intra-cluster medium (ICM). This process creates several distinct signatures, including…

Dust-driven streaming instability and magnetic field amplification downstream of supernova remnant shocks

S. Gabici, J. C. Raymond, A. Ciardi +3

The acceleration of cosmic rays up to PeV energies at supernova remnant shocks requires an amplification of the ambient magnetic field. The amplification mechanism must operate ups…

SDSS-V LVM: Collisionless Shocks in the Supernova Remnant RCW86

Sumit K. Sarbadhicary, Knox S. Long, John C. Raymond +19

The supernova remnant (SNR) RCW86 is among the few SNRs with Balmer-emission lines containing broad and narrow spectral components that trace fast, non-radiative shocks in partiall…

Cassiopeia A's Reverse Shock and its Effects on the Expanding SN Ejecta

Robert A. Fesen, Dan Milisavljevic, Daniel Patnaude +4

Using optical and near-infrared images of the Cassiopeia A (Cas A) supernova remnant covering the time period 1951 to 2022, together with optical spectra of selected filaments, we…

The Green Monster hiding in front of Cas A: JWST reveals a dense and dusty circumstellar structure pockmarked by ejecta interactions

Ilse De Looze, Dan Milisavljevic, Tea Temim +27

JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W…

Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism

Tea Temim, J. Martin Laming, P. J. Kavanagh +19

We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…
